My wagon turntables were only designed to turn 90 degrees. Enough for the job, but not suitable to turn a loco around. Someone asked me for a new version of one of my wagon turntables. This I did, then they said they wanted it to turn a small railcar around, so I had to do some thinking. As the item was in production I started working ideas on how the mechanism could be modified. Not perfect, but the ideas generated made me think I could produce something more like a loco turntable. I came up with the following

It is no thicker than a piece of track, so no well to cut into baseboard. If the mechanism I designed is used then it needs an extra few mm. It is intended to look like a standard deck type turntable, but obviously the pit is fake. I saw a photo showing pit filled with water, so mucky it up and it could look like it was filled with water.It is 84mm long, which is big enough for a wide range of small locos. Gauge on this one is 16.5mm but I aim to do it in other gauges.
